Senior Principal Engineer, Hardware Application Engineering - Signal Integrity & Power Integrity

Responsibilities

• Serve as the senior SI/PI technical authority for customer platforms built on Marvell's Ethernet switches and UALink silicon, from early channel definition through mass-production qualification.
• Define and maintain layout and routing guidelines for high-speed SerDes channels, power delivery networks, and sensitive analog interfaces - and drive their adoption with customers, ODMs, and internal teams.
• Perform post-silicon channel extraction, full-channel simulation, and what-if analysis on customer board designs, and recommend targeted layout and stack-up fixes that move designs from "passing" to "best-in-class margins."
• Lead compliance testing and lab characterization - BER/SER, eye-opening margins, jitter, return loss, crosstalk - and translate measurement data into actionable design and SerDes-tuning guidance.
• Provide SerDes tuning guidance to customers based on simulation results, lab measurements, and field telemetry; partner with Marvell silicon teams to refine tuning methodologies.
• Run and review power integrity simulations covering PDN impedance, IR drop, decoupling effectiveness, transient response, and droop, and guide customers on robust PDN architectures for high-current ASICs.
• Translate customer power needs and constraints into structured feedback for Marvell silicon, packaging, and platform engineering teams - closing the loop for continuous product improvement.
• Engage directly with ODMs on SI/PI guidance, design reviews, and qualification activities, partnering with the global Customer Solutions Group and internal engineering teams.
• Support definition and validation of reference designs for new Marvell silicon - owning the SI/PI side of the design from early channel budgeting through customer release.
• Provide hands-on lab debug expertise during customer bring-up and production ramp, using VNAs, BERTs, real-time scopes, TDR equipment, jitter analyzers, and compliance test kits.
• Develop and deliver SI/PI training to customers, ODMs, and internal Marvell teams - covering high-speed design best practices, simulation methodology, and lab debug techniques.
• Provide technical leadership on 112G and 224G PAM4 SerDes designs today, and help shape Marvell's SI/PI approach for next-generation 448G systems.
• Partner closely with Marvell Silicon Design, Packaging, Board/System HW, Software, and Operations teams to deliver fully integrated solutions.
• Contribute to product definition and roadmap planning by bringing real-world SI/PI insights into architecture and marketing discussions.
• Represent Marvell's SI/PI expertise in customer briefings, executive reviews, and industry technical
